Connect to AWS

After creating a environment create a connection between the AWS and GigaVUE‑FM. Refer to the following step given below for detailed information on how to create a new connection.

Create Connection

To create a new Connection:

Select Inventory > Resources > Environment.
On the Environments page, on the Connections tab, click Create.
The Create New Connection dialog box opens. Enter the details as mentioned in the below section.
Note: When creating a connection in the connections page, the corresponding monitoring domain created for internal use in GigaVUE‑FM will not be displayed in the Monitoring Domain list page.

Note: For Application Intelligence solution, you must add the UDP port 2056 for GigaVUE‑FM in your AWS security group.

To connect to AWS, select or enter the following details:

Field

Description

Name

Name used to identify the connection.

Credential

Select your credentials from the drop-down menu. Refer Create Credentials for detailed information on how to create credentials.

Secret Region

The AWS region for the connection. For example, EU (London).

Note: If the region you want to choose is not available in the Region Name list, you can add a custom region.

Adding a Custom Region

To add a custom region:

In the Region Name drop-down list, select Custom Region.

In the Custom Region Name field, enter the name of the region that is not available in the list.

Select Account

Select the AWS account name/id.

Select VPCs

Select the VPC

Traffic Acquisition Method

Select a Tapping method. The available options are:

■

G-vTAP: If you select G-vTAP as the tapping method, you must configure the G-vTAP Controller to monitor the G-vTAP Agents. You can also configure the G-vTAP Controller and G-vTAP Agents using your own orchestor. Refer to Configure GigaVUE Fabric Components in AWS for detailed information.

■

VPC Traffic Mirroring: If you select VPC Traffic Mirroring option as tapping method, only nitro-based agent is support. If you wish to use an external load balancer (optional). Select Yes to use a load balancer. Refer to Configure an External Load Balancer on GigaVUE Cloud Suite for AWS and Configure a Gateway Load Balancer on GigaVUE Cloud Suite in AWS for detailed information. G-vTAP Controller configuration is not required for VPC Traffic Mirroring.

■

Tunnel: If you use select Tunnel as the tapping method, you can select the tunnel as a source where the traffic is directly tunneled to GigaVUE V Series Nodes without deploying G-vTAP Agents or G-vTAP controllers..

Note: For VPC Traffic Mirroring option, additional permissions are required. Refer to the Permissions and Privileges for details.

MTU

The Maximum Transmission Unit (MTU) is the maximum size of each packet that the tunnel endpoint can carry.

Note: The default MTU is 1450. You can edit the MTU value according to your requirements. The valid range is between 1450 to 9000.

The elastic IP address does not change when you stop or start the instance.

Additional Subnets

(Optional) If there are GigaVUE V Series Nodes on subnets that are not IP routable from the management subnet, additional subnets must be specified so that the GigaVUE V Series Proxy can communicate with all the GigaVUE V Series Nodes.

Click Add to specify additional subnets, if needed. Also, make sure that you specify a list of security groups for each additional subnet.

In the G-vTAP Configuration section, select or enter the following details:

Fields

Description

Controller Version

The G-vTAP Controller version. If there are multiple versions of G-vTAP Agents deployed in the EC2 instances, then you must configure multiple versions of G-vTAP Controllers that matches the version numbers of the G-vTAP Agents.

Note: If there is a version mismatch between G-vTAP controllers and G-vTAP Agents, GigaVUE-FM cannot detect the agents in the instances.

Click Add to add multiple versions of G-vTAP Controllers:

An older version of G-vTAP Controller can be deleted once all the G-vTAP Agents are upgraded to the latest version.

Instance Type

The instance type for the G-vTAP controller. The recommended minimum instance type is nitro-based starting from t2.micro.

Note: V Series 2 solution does not support non-nitro-based instance types.

Agent Tunnel Type

The type of tunnel used for sending the traffic from G-vTAP Agents to GigaVUE V Series nodes. The options are GRE or VXLAN tunnels. If any Windows agents co-exist with Linux agents, VXLAN must be selected.

G-vTAP Agent MTU (Maximum Transmission Unit)

The Maximum Transmission Unit (MTU) is the maximum size of each packet that the tunnel endpoint can carry from the G-vTAP Agent to the GigaVUE V Series node.

In AWS, the default value is 9000.
For VXLAN, the default value is 8951. The G-vTAP Agent tunnel MTU must be at least 50 bytes less than the agent's destination interface MTU size.
For GRE, the default MTU setting must be at least 42 bytes less than the default MTU.

AWS Platform MTU is 9000

■

With agent tunnel type L2GRE and ‘Secure Mirror Traffic’ option enabled, G-vTAP Agent Tunnel MTU should be set as (9000-42-53) = 8905.

■

With agent tunnel type L2GRE and ‘Secure Mirror Traffic’ option disabled, G-vTAP Agent Tunnel MTU should be configured as (9000-42) = 8958.

■

With agent tunnel type VXLAN and ‘Secure Mirror Traffic’ option enabled, G-vTAP Agent Tunnel MTU should be (9000-50-53) = 8897.

■

With agent tunnel type VXLAN and ‘Secure Mirror Traffic’ option disabled, G-vTAP Agent Tunnel MTU should be 8951.

IP Address Type

The IP address type. Select one of the following:

■

Select Private if you want to assign an IP address that is not reachable over Internet. You can use private IP address for communication between the G-vTAP Controller and GigaVUE-FM.

■

Select Public if you want the IP address to be assigned from Amazon’s pool of public IP address. The public IP address gets changed every time the instance is stopped and restarted.

■

Select Elastic if you want a static public IP address for your instance. Ensure to have the available elastic IP address in your VPC.

Note: The elastic IP address does not change when you stop or start the instance.
